With only a single ingredient, Raspberry Ketone by AI Sports Nutrition is designed to optimize fat loss by stimulating fat cells to “mobilize and excrete their fatty acids.”

Raspberry ketones gained a lot of attention after it was described as a “miracle in a bottle” on an episode of Dr. Oz. [1]

But are raspberry ketones effective in supporting weight loss goals or is supporting evidence lacking? I took a closer took to find out.

What Does Science Say About Raspberry Ketone?

In each serving of AI Sports Raspberry Ketone there is 500 mg raspberry ketone.

Raspberry ketone is a phenolic compound found in raspberries that gives this fruit its scent. [2] While one prominent Japanese study shows it may affect body composition in animals, conclusive human clinical evidence surrounding its weight loss benefits is lacking.

In one study, researchers administered raspberry ketone to mice fed a high-fat diet for several weeks.

Research shows raspberry ketone supplementation “prevented the high-fat-diet-induced elevations in body weight and the weights of the liver and visceral adipose tissues.” These effects are attributed to raspberry ketone’s ability to alter lipid metabolism. [3]

How Much Is AI Sports Raspberry Ketone?

The best deals I found were on eSupplements.com, where the product is backed by a 60-day money-back guarantee. This guarantee applies to 1 used and any unused AI Sports Raspberry Ketone bottles purchased through this website.

How Often Should You Take It?

Users should take 1-2 capsules about 2-3 times a day. For optimal use, Raspberry Ketone should be taken 30 minutes before meals.

Raspberry Ketone may work differently in users, so some may wish to assess tolerance in the beginning by taking a smaller dose per serving.

Are There Side Effects?

Because raspberry ketone is chemically related to synephrine, a stimulant, some researchers believe some users may experience jitteriness, rapid heartbeat, and increases in blood pressure. [6]

What Does the Supplement Community Say About It?

Reviews surrounding AI Sports Raspberry Ketone are mixed. Some users noticed improvements in weight loss and some didn’t notice anything at all. Here is a closer look at what some users have to say:

“I have followed directions and I haven’t lost a pound!” says Sharon Rogers on SuperSup.com. “I am on a rigid diet and thought this product would speed up my weight loss…but instead I haven’t lost ANY weight… so I quit taking it to see if I start losing again with out it.”

Another SuperSup.com user, Woman in her 40s, says she noticed a difference after taking AI Sports Raspberry Ketone for 3 days. She took 1 capsule two times a day and has since increased the dose to 3 capsules twice a day. She notes benefits are more noticeable when she restricts her diet to only protein and a low carb diet.

Rsadamsjr1, a user on BodyBuilding.com, bought AI Sports Raspberry Ketones for his wife and says while she hasn’t noticed tons of weight loss, “she is shedding inches.” He notes she is back in her “skinny clothes” after just a week and a half of taking it.

Should You Buy AI Sports Raspberry Ketone?

Until sufficient human clinical research comes forward, I remain hesitant to give this supplement my full support.

However, it appears to work on some users in conjunction with a healthy diet and exercise, and the animal studies are promising.

So, if you are interested in purchasing AI Sports Raspberry Ketone, go through eSupplements.com. Its guarantee essentially eliminates the financial concern that some consumers may have of trying potential weight loss aids.
